Various devices that I don't want to install the official software or drivers to control. I've done this with several things, but just as an example I have a MIDI MPC pad (the sort of thing samplers/beat makers use) and worked out it had various features not supported officially like controlling the lights on the pads. I also discovered some cheap Chinese lights my daughter owns are controllable over BLE without encryption.
